A Mojave Desert shrub community was experimentally burned to understand changes in seed bank of desert annual plant species in response to wildfire. Seed mortality ranged from 55 to 80%, and fire caused significant losses of native and alien annual seeds. Schismus arabicus, Schismus barbatus, Bromus madritensis, Bromus tectorum, Erodium cicutarium and Plantago spp. made up >95% of the seed bank...
Rhynchosporium consists of two species, R. secalis and R. orthosporum. Both are pathogens of grasses with R. secalis infecting a variety of Poaceae hosts and R. orthosporum infecting Dactylis glomerata. Phylogenetic analyses of multilocus DNA sequence data on R. secalis isolates originating from cultivated barley, rye, triticale and other grasses, including Agropyron spp., Bromus diandrus and H...
Here, we report the draft genome sequence of the Xanthomonas bromi type strain LMG 947, an important pathogen of bromegrasses (Bromus spp.). Comparative analysis with other Xanthomonas spp. that are pathogenic on forage grasses will assist the analysis of host-plant adaptation at the genome level.
Bradley N. Johnson Tami L. Stubbs Land Management and Water Conservation Research Unit, USDA Agricultural Research Service, 215 Johnson Hall, Washington State University, Pullman, WA, 99164-6421 Pseudomonas fluorescens strain D7 (P. f. D7; NRRL B-18293) is a root-colonizing bacterium that inhibits downy brome (Bromus tectorum L. BROTE) growth. Before commercialization as a biological control ag...
Bromus sect. Triniusa is revised in Khorassan based on the new taxonomic concepts of Bromus danthoniae complex group and a remarkable herbarium material collected from Khorassan (Kopetdagh, northeastern Iran), as the main center of its diversity. Bromus turcomanicus, a narrow endemic species in central Kopetdagh hitherto known only from the type locality in southern Turkmenistan, is newly recor...
Chromosome morphometry and nuclear DNA content are useful data for cytotaxonomy and to understand the evolutionary history of different taxa. For the genus Bromus Linnaeus, 1753, distinct ploidy levels have been reported, occurring from diploid to duodecaploid species. The geographic distribution of Bromus species has been correlated with chromosome number and ploidy level. In this study, the a...
A prominent goal of invasive plant management is to prevent or reduce the spread of invasive species into uninvaded landscapes and regions. Monitoring and control efforts often rely on scientific knowledge of suitable habitat for the invasive species. However, rising temperatures and altered precipitation projected with climate change are likely to shift the geographic range of that suitable ha...
استفاده از تنوع ژنتیکی در منابع گیاهان زراعی یکی از راهکارهای مهم در راستای کشاورزی پایدار است. بهمنظور شناسایی ژرمپلاسمهای علوفهای متحمل به سرما، تعداد 124 توده در قالب 40 گونه و 9 جنس از گیاهان علوفهای یکساله حاصل آزمایشهای قبلی از جنسهای شبدر(Trifolium spp)، یونجه یکساله (Medicago spp)، اسپرس (Onobrychis spp)، ماشک (Vicia spp)، شبدر شیرین (Melilotus spp)، لولیوم (Lolium spp)، برومو...
